Amazon Cognito now supports multi-Region replication

Amazon Cognito Multi-Region Replication

Amazon Cognito now supports multi-Region replication, enabling you to synchronize user and machine identity data to a secondary user pool in a standby Region in near real-time. This improves the resilience of your authentication system by providing a standby replica that can accept traffic in case of a regional service disruption.

In the event of a disruption in the primary Region, you can redirect traffic to the secondary user pool. Signed-in users continue accessing their applications without re-authenticating, and registered users can sign in with their existing credentials. Authentication methods continue to work in the secondary Region, including username/password, federation with social identity and SAML/OIDC providers, and machine-to-machine authorization flows.

What to do

• Configure multi-Region replication using the AWS Management Console, AWS CLI, or AWS SDKs by adding a replica user pool.
• Visit the pricing page for pricing details.
• Refer to the developer guide for instructions.
